Lew still working on signature

Treasury Secretary Jack Lew says he still has some work to do on his penmanship despite his new, less loopy signature on U.S. currency.

Asked on "Fox News Sunday" by host Chris Wallace how he was able to come up with a more mainstream signature, Lew said he's been working at a more conventional signature for many years, an effort that remains a work in progress.

"Chris, I have been working on my handwriting for many decades. And I obviously still have some more work to do," Lew said. "I will confess to having a certain challenge with penmanship. And I always do my best."
